For what it is worth Chevy built the base 71-72 C/10s without power brakes. The J70 booster was optional but also required with some options like any of these: A/C, P/S, 402 BBC, Aux Battery, Step Bumper, Four Speed Trans and more.

IMHO, based on your signature, you should have power brakes if running factory disc brakes. To delete a booster just to clean things up doesn't make much sense to me nor sound too safe in today's driving enviroment full of inattentive idiots with ABS.
